On the arch AB are a couple of forces (F1, F'1) and the force F. Determine the sum of the moments about point A, if the force F = 4 N, F1 = 2 H, the radius r = 2 m, shoulder CD = 1,5 m .

You will receive a solution to the problem 2.1.8 (Chapter 1 - statics topic - 2.1: Moment of a force about a point. A moment of couple) in theoretical mechanics from the collection of short tasks Kep OE, H. A. Viba, OP Grapis, JA Svetinysh and others. Publishing Moscow / Graduate School / 1989, 2009, 2012. The task is made in the format word (typed or hand-written decision in a Word) or in manuscript form in the format gif, packed to the archive zip (open on any PC) .After checking the solutions would be very grateful if you leave your positive feedback.
